Hi Ravi,
You can perform the inner join on two table in select statement.
you can create the data type with 13 elements (10 from table A and 3 table B as 3 of table is already covered in table A). the message or data comes from database is in recordset.
you can write the query
select A.1, A.2....A.10,B.4, B.5, B.6 from A inner join A on A.1 =B.1
Please test your query on the database. please also refer the below discussion
